As Greenland’s glaciers retreat, they are losing ice at a faster and faster rate.
Greenland's glaciers have retreated so far that they can no longer support the ice sheet that feeds them. The ice sheet system has reached a new normal of consistent annual ice loss.

Satellite research confirms its enormous ice sheet is melting faster than most scientists predicted.
The research vessel must dodge dangerous icebergs as it drills for sediment core samples.
A paleooceanographer describes her ninth sea expedition, this time retrieving cylindrical 'cores' of the sediment and rock that's as much as two miles down at the ocean floor.

We used 11 different satellite missions to track Antarctica’s contribution to rising sea levels.
The crew of scientists prepare to put the drill stem into the Greenland ice sheet to probe water flows about a half of a mile below.
A glaciologist develops a lightweight method for probing the depths of Greenland's ice sheet to answer a crucial question: How fast is it melting?
Knowing where the ice comes from can help work out what it will do to sea levels.
Polar ice isn't all the same - it can be divided roughly into "land ice" and "sea ice". What matters most for sea levels is how much ice slides off the land and melts in the sea.
Adélie Penguins struggle to reach their nesting sites if there’s too much ice in the way.
Despite their image as cold-loving creatures, Adélie penguins could be winners from climate change.
Antarctica is vital to the planet’s climate system.

Why should we care if the polar ice sheets melt hundreds of years in the future? Because they are vital for maintaining our current climate.
How much staying power? A calving front of the Antarctic ice sheet.
If we burned all fossil fuels, the loss of ice in Antarctica would raise sea levels 160 to 200 feet, but even our current trajectory could lead to dramatic sea level rise.
Study raises new questions over the rate of ice melting, and thus sea level rise.
NASA's former climate chief, James Hansen, is lead author on a paper that predicts rapidly rising seas this century, but not all climate scientists believe the study's models are convincing.

Researchers find that ice around Antarctica shrank quickly last decade, raising concerns over this buttress against melting land-based ice and future sea-level rise.
The Thwaites Glacier is among several in West Antarctica that is already retreating.
Antarctic climate science is having a moment – a worrying moment. Three new studies have all concluded that the West Antarctic Ice Sheet has begun to collapse. This collapse will impact humanity for generations…
Climate change is causing the North Pole to shift, owing to subtle changes in Earth’s rotation that result from the melting…
Antarctic ice shelves are losing ice by melting from their undersides, as well as by calving icebergs. A study compiled by…

A previously unknown canyon has been discovered in Greenland, hidden beneath the ice. It is at least 750 kilometres long…
Findings from a large-scale ice drilling study on the Greenland ice sheet may revise the models used to predict how ice sheets…
The cause of dramatic losses in glaciers and ice sheets in the West Antarctic is still unclear. A recent research team has…
